My only comment would be that if you coated the car in primer as I did using a PPG 2K epoxy primer and not the regular rattle can stuff, you would be ok. The hardened epoxy primer is tuff as nails and not porous.
I believe PPG recommends you always have a top coat. Tough as nail ... when out of the sun and moisture. Ask your ppg rep.
Here is a comment from another forum..

But the main reason I brought this up is IF you plan on driving the car for any extended periods of time with the car being left outside in the weather and the sun beating down on it you will have problems later. There is NO sun UV protection in epoxy primer so the UV rays will start destroying the primer on a molecular level with the end result of serious adhesion problems later. And if the car sits outside in the rain (or snow) eventually the moisture will penetrate through the primer to metal and cause rust problems.
So to make a long story short -- you can epoxy primer panels and let them sit for extended periods of time IF the car is left high and dry in a garage out of the weather.
